Methods of Preparation
Start with the big picture
Preparation methods vary with the metal, ligands, and desired reactivity. Direct reaction of a metal with an alkyl or aryl halide can form simple organometallics, while salt metathesis, transmetalation, and metal–halogen exchange transfer organic groups between metal centers. Other routes create or modify metal–carbon bonds through reduction, oxidative addition, addition across unsaturated bonds, or insertion of carbon monoxide and alkenes. The topic also covers approaches such as carbonylation, metal vapor synthesis, and ligand substitution. Together, these methods provide a framework for understanding how organometallic compounds are assembled and why different strategies suit different targets.
What you'll learn
